Solving Real-World Data Fetching Challenges with Next.js and TanStack Query: A Pragmatic Case Study

Speaker Fariz Aziz dives into the typical frontend headaches—too many network requests, inefficient caching, resilience gaps, and bloated API payloads—using a real-world fintech scenario. By introducing a Backend-for-Frontend (BFF) pattern and leveraging Next.js for server-side rendering and API routing, his team trimmed down payload sizes, streamlined caching, and improved overall performance under heavy third-party usage.

On the client side, TanStack Query takes care of state management, minimizes re-renders, and keeps things resilient. With live demos and practical tips, you’ll learn how to evolve from basic fetch calls to robust, scalable data-fetching workflows that empower frontend teams despite backend constraints.
